1 Chronicles 10:6

The battle went hard against Saul, and the archers overtook him; and he was distressed by reason of the archers.

Then Saul said to his armor bearer, “Draw your sword, and thrust me through with it, lest these uncircumcised come and abuse me.”

But his armor bearer would not, for he was terrified. Therefore Saul took his sword and fell on it.

When his armor bearer saw that Saul was dead, he likewise fell on his sword and died.

When all the men of Israel who were in the valley saw that they fled, and that Saul and his sons were dead, they abandoned their cities, and fled; and the Philistines came and lived in them.

On the next day, when the Philistines came to strip the slain, they found Saul and his sons fallen on Mount Gilboa.

They stripped him and took his head and his armor, then sent into the land of the Philistines all around to carry the news to their idols and to the people.
